摘要：
This invention is intended to establish a technology that can effectively utilize manganese byproducts produced in the course of manufacturing lectrolytic manganese dioxide and provide a novel manganese fertilizer that fertilizer response can operates both readily available and slow-release. According to the invention, there is provided a manganese fertilizer comprising manganese byproducts produced in characterized in that it contains at least citric acid-soluble manganese (C-MnO) by 3 to 20wt% and water-soluble manganese (W-MnO) by 0.5 to 7.0wt%.
